Grayscale musculoskeletal sonography represents a cost-effective, readily available diagnostic imaging modality that has gained popularity in musculoskeletal and sports medicine to evaluate injuries of various tissue types. Recent studies have demonstrated the applications of new imaging modes/softwares that can help improve our clinical characterization of soft tissue injuries. This session will cover 3 newer modes of musculoskeletal ultrasound, namely elastography, ultrasound tissue characterization (UTC), and MuscleSound (MS) and the existing clinical evidence and potential research applications of these technologies. Elastography measures tissue stiffness, and this technology improves our ability to detect tissue softening, which is useful in evaluating tendinopathies. UTC can help analyze tendons in detail via three-dimensional rendering of targeted tendons using 600 still images, allowing quantification of cross sectional area and percentage of normal tendon fibers vs. disorganized fibers, and can offer improved characterization of tendon tissues. Finally, MS allows measurement of muscle glycogen content as glycogen depletion and fatigue are associated with increased injury risks.
